Key Features
- 130 mV typical dropout voltage at 500 mA output minimizes power dissipation in low-headroom portable designs
- Ultra-compact 4-ball WCSP package at 0.63 mm x 0.63 mm enables densely packed wearable and IoT PCB layouts
- Fixed 3.3 V output with line regulation of 0.002376% ensures stable supply for sensitive analog and digital loads
Applications
The TPS7A2133PYWDJ is optimized for wearable health monitors, miniature IoT sensor nodes, and portable consumer electronics that require a tightly regulated 3.3 V rail with minimal dropout from a Li-ion or USB 5 V supply. Its extremely small WCSP footprint allows placement directly under a microcontroller or RF module to reduce trace length and improve noise performance. It also suits smartwatch power trees and hearing aid electronics where board area below 1 mm2 per regulator is a hard constraint.

Frequently Asked Questions
What is the dropout voltage of TPS7A2133PYWDJ at full 500 mA load, and why does it matter for Li-ion applications?
At full 500 mA output, the TPS7A2133PYWDJ has a typical dropout voltage of 130 mV and a maximum of 175 mV. For a Li-ion cell discharging from 4.2 V to 3.6 V, this means the 3.3 V output remains regulated until the cell reaches approximately 3.475 V, extending useful run time compared to regulators with 300 mV or higher dropout.
How does the 4-ball WCSP package of TPS7A2133PYWDJ reduce board area in a wearable PCB design?
The 4-ball WCSP measures only 0.63 mm x 0.63 mm, which is roughly 80% smaller than a comparable SOT-23-5 package. In a wearable device with a 15 mm x 25 mm PCB, using the WCSP frees approximately 4 mm2 per regulator, enough to accommodate additional decoupling capacitors or a secondary sensor IC on the same layer.
For a USB-powered IoT hub, when should a designer select TPS7A2133PYWDJ instead of a switching regulator to power a 3.3 V MCU rail?
When the load current stays below 250 mA and the input is 5 V USB, the power dissipation is (5 V minus 3.3 V) x 0.25 A = 425 mW, which is acceptable for short duty cycles. The LDO eliminates switching noise on the 3.3 V rail, benefiting ADC accuracy and RF sensitivity, and removes the need for the larger inductor required by a buck converter.
